Aguilera takes a different route. Yeah, she's still ticked and gives a laundry list of the wrongs done to her: lying, cheating, manipulation, etc. But she's going to be the better person and learn from it. Scott Storch, who previously wrote with Jill Scott, and Aguilera each have a songwriting credit. The work is up to par. Unlike most angry songs, Fighter actually explains what betrayals happened and that it changed the person. The standout verse is the first: "after all the stealing and cheating/You probably think I hold resentment for you…/'Cause if it wasn't for all that you tried to do/I wouldn't know/Just how capable I am to pull through/So I want to say thank you."

Aguilera's vocals are on point. Again, she uses the natural strength in her voice to convey the emotions needed i.e. vulnerability, naivete, and confidence to name a few. Rock-pop, however, is a genre she needs to grow into. Fighter is a great start and in time she will mature in this genre as she has R&B.
